How does this code snippet work?

Question

I came across this snippet recently which turns a binary number into a decimal number, but I don't understand how it happens.

print(int('101010',2))
# output 42

Answer 1

Syntax: the 2. argument in int is the base of the numbers which converts the string of that number base to an integer.

Binary numbers:
From left to right multiply 2^(index) with the current value. In this case: 1* 2^5 + 0* 2^4 + 1*2^3 + 0 *2^2 + 1* 2^1 + 0*2^0 = 32+8+2=42
